Barcelona and Paris Saint-Germain go head-to-head in Champions League

Paris Saint-Germain and Barcelona meet in the Champions League on Wednesday in a clash between two of the favourites to win the competition this season. Defending champion PSG is aiming to join Real Madrid as the only team to retain the title in the modern era. Madrid won it three times in a row from 2016-18. Other than that, no team has won it in back-to-back years since the European Cup was rebranded as the Champions League in 1992.
